Bulk bag will be positioned onto hooks of crane adapter. Using pendent control, adapter and bag can now be lifted and placed onto bag receiver hopper. By opening access door operator can feed bag spout into access box, untie spout, (material can now flow into downstream equipment) then close access door. Once “Start” button has been hit, bag unloader gyrator will start and material will flow.
If optional iris valve is used, the bag spout will be pulled through the open iris valve prior to untying bag discharge spout. Iris valve can then be closed prior to dispensing and set at one of many intermittent positions for metering material. When valve is closed the bag spout can be retied and removed from unloader if desired.
